Trivia / Inai Inai Baa!

• Breakaway Pop Hit: "Popopopopose", one of the songs on this show, became this when J-Pop group GReeeeN covered it, inspiring a YouTube dance challenge. Their cover is also the top result for the song in search engines.
• Breaking News Interruption: The April 13, 2023 morning broadcast of the show, which was to introduce "Poupo's Drawing Song", was pre-empted by news of a missle from North Korea being fired over Hokkaido. The episode eventually premiered in the show's afternoon timeslot.
• Children Voicing Children: Mushimushi-kun, the main character in the segments of the same name, is voiced by an actual child.
• Content Leak:
  • Studio Mario leaked Yuki-chan's outfit five months before she first appeared on the show. It's justified, as November is usually when the auditions for the next onee-san are held.
  • The official DVD listing for "Yahoo" leaked the title of a "Poupo's I Did It!" segment called "Ohayou Poupo" a month before it was broadcast. Usually, NHK is secretive about new Inai Inai Baa! episodes and only releases the titles of new segments 5 days before broadcast.
• Cowboy BeBop at His Computer:
  • The 20th anniversary DVD contains a segment labeled as Kana-chan's first appearance, except it's not. She's wearing her second costume, and Kuu, the show's second puppet character, is in the segment. It's likely they used a segment from the first time the costume and Kuu appeared instead due to the Early-Installment Weirdness present in Kana's actual first appearance.
  • It's a common sight on Japanese shopping websites like Mercari to see pre-2003 merchandise listings call Kuu U-Tan. Justified, as more people are familiar with the seasons featuring U-Tan than the ones featuring Kuu. In at least one instance, Kuu was called Jean Jean, a character who mainly appears in the Wan Wan Wonderland live shows.
• Dawson Casting: Averted; the onee-san is always played by a girl between the ages of 5 and 13.
• Keep Circulating the Tapes: Like with other NHK shows, only select segments of this show ever get released to DVD, with some not seeing proper releases.
• Live on Stage!: The Wan-Wan Wonderland shows are of this type, being shows that tour Japan for limited periods of time in Japan. In the shows, the characters sing the hit songs from the series. Wanwan and several oneesans also appeared in several NHK live shows combining all of their children's series.
• Never Work with Children or Animals: Applies to the segments where Wanwan and the oneesan interact with babies. Very often, it's easy to notice that some of the babies are not paying attention to whatever activity they are doing, and instead are running off to do something else or are sitting on the floor. This is justified, as the activities performed are sometimes difficult for children of that age to do.
• No Export for You: Averted for the most part since most international NHK feeds carry the show, but there have been no localizations of it other than the Vietamese version, Ú Òa, a Myanmar version and a Chinese version.
  • Played straight with the show's streaming reach. Netflix has only made the show available to a very small amount of countries. For the rest of the world, the only option is the NHK World Premium satellite channel, a separate channel that is available on less providers compared to it's NHK World sibling.
  • This will soon be averted for the United States, Trinidad, Tobago and Mexico, as a program called WanWan The World confirmed that a Spanish dub ("Donde Estoy? Aqui!") airs on Canal 22 in Mexico during the Clic Clac block, and an English dub ("Peek-a-boo!") is currently in production.
• The Other Darrin: Kuu-chan was voiced by Emi Motoi when Taeko Kawata took maternity leave.
• Pop-Culture Urban Legends: In the mid-2010s, a rumor circulated the Japanese internet that Mana Ashida was one of the babies on this show during the Fuuka-chan era. This Yahoo Answers entry explains that Mana would've been too old to participate in the show in 2007, and that people were likely confusing this for Fuku Suzuki's appearance on the show, which happened in 2006.
• Recycled Script: When Penta was replaced with Kuu in 1997, some of the animations for the "Can You Do It?" songs, and in some cases the audio of the songs, was recycled. The biggest example of this was "Tomodachi Hahaha", which uses the same props, background and facial expressions for the characters. The only differences between the Penta and Kuu versions are the pre-song intro having a different script and several scenes with Kuu and his cloud friend flying being added, specifically during the part that tells you what you can't do to a friend and at the end of the song.
• Similarly Named Works: Both this show and Okaasan to Issho have a song called "Kaze no Ohanashi". While the names are identical, the music and lyrics are different for both.
• Unfinished Dub: While the show has been running for over 25 years in Japan, all of the dubs that have been produced don't cover the entire series. The Chinese dub that was made prior to the co-production only dubbed 52 episodes of the Fuuka-chan era, and the English and Spanish dubs only did 100 episodes featuring Yuki-chan.
• What Could Have Been: The pilot version of the show featured different looks for Wan Wan and Kana-chan. Wan Wan was grey with orange ears, and Kana-chan wore a pink bunny costume instead of a poodle costume. The set was also circus-themed instead of taking place in a forest.
